This is a three strand bold necklace with a strand of light green turquoise, a strand of faceted purple and faceted green amethyst.
They are securely joined together with wire and sterling endcaps and finished off with handmade Sterling chain.
The chain and the sterling lobster claw clasp makes the necklace adjustable from 17 to 19 inches. The necklace is more sparkly in real life than in the pictures
